Shure A95U
UPC/EAN #042406053846
MPN #A95U
Line Matching Transformer, Low Impedance Male XLR to High Impedance MC1M Connector with Mating 1/4-inch Phone Plug/Jack.
This reversible transformer matches low- or high-impedance microphones to high- or low-impedance inputs. The transformer permits use of very long microphone cables with either low- or high-impedance microphones. However, when connecting a high-impedance microphone, limit the cable length between the microphone and the transformer to 4.6 m (15 foot). The cable from the transformer to the low-impedance input can be any desired length.
The transformer prevents high-frequency loss, level loss, and pickup of noise and hum. The A95U comes furnished with a three-pin XLR connector on the low-impedance end, with a 1/4 inch phone plug and phone jack adapter on the high-impedance end.
